JOHN FORHAN, OF NEW YORK, N. Y.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 247,246, dated September 20, 1881.

Application led June 20, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN FORHAN, of the city, county, and Sta-te of New York, have invented an Improved Screen for Windows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this spec`1` cation.

My invention relates to a screen adapted to be placed in or itted to a window-opening, to prevent the entrance through the window, when open, of gnats or other annoying insects; and it. consists in a window-screen composed of the parts hereinafter particularly described, combined and arranged to operate as hereinafter specitied.

Figure l is a front elevation of a windowscreen embodying my invention, and showing the same in position in a window-frame. Fig. 2 is a cross-section on the linem'x, Fig. l. Fig. 3 is an enlarged cross-section on line y y of Fig. l; and Fig. 4 is a perspective view, in detail, of the elastic rubber band which I preferably employ to actuate one of the rollers ot my improved device.

In carrying out my invention I employ two cylinders or rollers, A and B, which may be ot' wood or metal, and which are of suitable Adiameter and are each of a length sufficient to extend from one edge of the window or sash opening to the other, along one side thereof, as seen in Fig. l.; and I nd it preferable to use as these rollers the ordinary wooden shaderollers, such as are well known in the trade. To one of these rollers, and longitudinally thereof, I attach by means of tacks or otherwise one edge of the sheet or piece of gauze or netting C, and to the other rollerI secure the opposite edge of said gauze or netting in a similar manner.

vrlhe gauze or netting C may be of woven wire or the ordinary mosquito-netting, and should be of an area sufficient to wholly cover the window or sash opening, as seen in Fig. l, and its length from its junction with one roller to the other` should be preferably somewhat greater than the distance between the opposite sides of the window-frame, to which the rollers are secured, as hereinafter specified, so that when the rollers are in position the netting or gauze must be rolled up more or less on the rollers, in order to bring it taut across the said window-opening between the rollers.

The roller A is placed at one side of the window-opening, along. the edge thereof and closely against the face of the window-frame D, and is held in position by meansof the axial pins a, one of which enters a suitable opening or bearing in the window-seat or end of the Window-frame, and the other has a bearing in an eye or staple, a', which is driven into the side of the window-frame. rlhis eye or staple a may be fixed at a distance from the end of the roller greater than the depth to which the axial pin on the opposite end ofthe roller enters its socket or bearing, and thereby the rollerbe conveniently detachable from its position, as described, without disturbing the staple or eye a'. The other roller, B, is similarly placed and secured in position on the window-frame at the opposite side ot the window or sash opening.

In order that the gauze or netting may be stretched and held taut across the windowopening, and its edges between the rollers be thus held in a right line against the edges ot' the sash and window-frame, I employ theJ following simple and inexpensive devices, namely: a pin, a2, driven into the exposed end ot' the roller to one side of the axis thereof, and extending from the end, so that it strikes against or engages the side of the eye or staple, which forms the bearin g for the axial pin on that end ofthe roller. The axis at the exposed end ofthe opposite roller; B, is composed of two pins, b b', set in the roller end, at opposite sides of the axial line, and over one of these pins, b, is looped an elastic rubber band, E, which is then carried double around the l other pin, b', and preferably thence back around the pin b, and then again around pin bf, to stretch the elastic band, and is then looped over a pin, d, fixed at a convenient point ou the window-frame, as seen plainly in Fig. 3. By this arrangement the elastic band operates to exert a constant and continuous force 011 the roller B'to rotate the same in its bearings, and to thus roll up the gauze O upon it, and consequently to draw the gauze taut across the window-opening, the roller A being held rigid, as described.

IOI

Itis evident that I have described a window-screen which is thoroughly effective for the purpose for which it is designed, and at the same time easily and cheaply constructed, readily putin place, does not need to be exactly fitted for each Windowr to whichI it is applied, as it fits itself thereto,and which, when not in use, can be rolled up in small compass, and stored in a limited space.

What I claim as my invention, and desire to secure by Letters Patent, is-

As a new manufacture, a screen for windows composed of the rollers A and B, attached to the opposite edges of the gauze or netting C, the roller Abeing provided with axial pins a, one having bearing in the end of the WindoW-frame D and the other in eye or staple a', xed in the side of said frame, and having the stop-pin a?, and the roller` B, having axial pin a at one end, with bearing in end of window-frame, and the double axial pin b b at the opposite end, with bearing in eye or staple a', together with the elastic band E, looped or coiled about said double pin and provided With holding-pin d, all constructed, combined, and arranged to operate substantially as and for the purpose specified.

Witness my hand this 10th day of June, A.
